FIELD OF THE INVENTION

The present invention is generally directed to antiviral compounds, andmore specifically directed to compounds which inhibit the functioning ofthe NS3 protease encoded by Hepatitis C virus (HCV), compositionscomprising such compounds and methods for inhibiting the functioning ofthe NS3 protease.

BACKGROUND OF THE INVENTION

HCV is a major human pathogen, infecting an estimated 170 millionpersons worldwide—roughly five times the number infected by humanimmunodeficiency virus type 1. A substantial fraction of these HCVinfected individuals develop serious progressive liver disease,including cirrhosis and hepatocellular carcinoma. (Lauer, G. M.; Walker,B. D. N. Engl. J. Med. (2001), 345, 41-52).

Presently, the most effective HCV therapy employs a combination ofalpha-interferon and ribavirin, leading to sustained efficacy in 40% ofpatients. (Poynard, T. et al. Lancet (1998), 352, 1426-1432). Recentclinical results demonstrate that pegylated alpha-interferon is superiorto unmodified alpha-interferon as monotherapy (Zeuzem, S. et al. N.Engl. J. Med. (2000), 343, 1666-1672). However, even with experimentaltherapeutic regimens involving combinations of pegylatedalpha-interferon and ribavirin, a substantial fraction of patients donot have a sustained reduction in viral load. Thus, there is a clear andlong-felt need to develop effective therapeutics for treatment of HCVinfection.

HCV is a positive-stranded RNA virus. Based on a comparison of thededuced amino acid sequence and the extensive similarity in the 5′untranslated region, HCV has been classified as a separate genus in theFlaviviridae family. All members of the Flaviviridae family haveenveloped virions that contain a positive stranded RNA genome encodingall known virus-specific proteins via translation of a single,uninterrupted, open reading frame.

Considerable heterogeneity is found within the nucleotide and encodedamino acid sequence throughout the HCV genome. At least six majorgenotypes have been characterized, and more than 50 subtypes have beendescribed. The major genotypes of HCV differ in their distributionworldwide, and the clinical significance of the genetic heterogeneity ofHCV remains elusive despite numerous studies of the possible effect ofgenotypes on pathogenesis and therapy.

The single strand HCV RNA genome is approximately 9500 nucleotides inlength and has a single open reading frame (ORF) encoding a single largepolyprotein of about 3000 amino acids. In infected cells, thispolyprotein is cleaved at multiple sites by cellular and viral proteasesto produce the structural and non-structural (NS) proteins. In the caseof HCV, the generation of mature non-structural proteins (NS2, NS3,NS4A, NS4B, NS5A, and NS5B) is effected by two viral proteases. Thefirst one, as yet poorly characterized, cleaves at the NS2-NS3 junction;the second one is a serine protease contained within the N-terminalregion of NS3 (henceforth referred to as NS3 protease) and mediates allthe subsequent cleavages downstream of NS3, both in cis, at the NS3-NS4Acleavage site, and in trans, for the remaining NS4A-NS4B, NS4B-NS5A,NS5A-NS5B sites. The NS4A protein appears to serve multiple functions,acting as a cofactor for the NS3 protease and possibly assisting in themembrane localization of NS3 and other viral replicase components. Thecomplex formation of the NS3 protein with NS4A seems necessary to theprocessing events, enhancing the proteolytic efficiency at all of thesites. The NS3 protein also exhibits nucleoside triphosphatase and RNAhelicase activities. NS5B is a RNA-dependent RNA polymerase that isinvolved in the replication of HCV.

Among the compounds that have demonstrated efficacy in inhibiting HCVreplication, as selective HCV serine protease inhibitors, are thepeptide compounds disclosed in U.S. Pat. No. 6,323,180.

DETAILED DESCRIPTION OF THE INVENTION

Stereochemical definitions and conventions used herein generally followMcGraw-Hill Dictionary of Chemical Terms, S. P. Parker, Ed., McGraw-HillBook Company, New York (1984) and Stereochemistry of Organic Compounds,Eliel, E. and Wilen, S., John Wiley & Sons, Inc., New York (1994). Manyorganic compounds exist in optically active forms, i.e., they have theability to rotate the plane of plane-polarized light. In describing anoptically active compound, the prefixes D and L or R and S are used todenote the absolute configuration of the molecule about its chiralcenter(s). The prefixes d and l or (+) and (−) are employed to designatethe sign of rotation of plane-polarized light by the compound, with (−)or l meaning that the compound is levorotatory and (+) or d, meaning thecompound, is dextrorotatory. For a given chemical structure, thesecompounds, called stereoisomers, are identical except that they aremirror images of one another. A specific stereoisomer of a mirror imagepair may also be referred to as an enantiomer, and a mixture of suchisomers is often called an enantiomeric mixture.

The nomenclature used to describe organic radicals, e.g., hydrocarbonsand substituted hydrocarbons, generally follows standard nomenclatureknown in the art, unless otherwise specifically defined. Combinations ofgroups, e.g., alkylalkoxyamine, include all possible stableconfigurations, unless otherwise specifically stated. Certain radicalsand combinations are defined below for purposes of illustration.

The terms “racemic mixture” and “racemate” refer to an equimolar mixtureof two enantiomeric species, devoid of optical activity.

The term “chiral” refers to molecules which have the property ofnon-superimposability of the mirror image partner, while the term“achiral” refers to molecules which are superimposable on their mirrorimage partner.

The term “stereoisomers” refers to compounds which have identicalchemical composition, but differ with regard to the arrangement of theatoms or groups in space.

The term “diastereomer” refers to a stereoisomer which is not anenantiomer, e.g., a stereoisomer with two or more centers of chiralityand whose molecules are not mirror images of one another. Diastereomershave different physical properties, e.g. melting points, boiling points,spectral properties, and reactivities. Mixtures of diastereomers mayseparate under high resolution analytical procedures such aselectrophoresis and chromatography.

The term “enantiomers” refers to two stereoisomers of a compound whichare non-superimposable mirror images of one another.

Thus, examples of such pharmaceutically acceptable saltsinclude chloride, bromide, iodide, sulfate, phosphate, methanesulfonate,citrate, acetate, malonate, fumarate, sulfamate, and tartrate.

Salts of an amine group may also comprise quaternary ammonium salts inwhich the amino nitrogen carries a suitable organic group such as analkyl, alkenyl, alkynyl or aralkyl moiety.

Compounds of the present invention, which are substituted with an acidicgroup, may exist as salts formed through base addition. Such baseaddition salts include those derived from inorganic bases which include,for example, alkali metal salts (e.g. sodium and potassium), alkalineearth metal salts (e.g. calcium and magnesium), aluminum salts andammonium salts. In addition, suitable base addition salts include saltsof physiologically acceptable organic bases such as trimethylamine,triethylamine, morpholine, pyridine, piperidine, picoline,dicyclohexylamine, N,N′-dibenzylethylenediamine, 2-hydroxyethylamine,bis-(2-hydroxyethyl)amine, tri-(2-hydroxyethyl)amine, procaine,dibenzylpiperidine, N-benzyl-β-phenethylamine, dehydroabietylamine,N,N′-bishydroabietylamine, glucamine, N-methylglucamine, collidine,quinine, quinoline, ethylenediamine, ornithine, choline,N,N′-benzylphenethylamine, chloroprocaine, diethanolamine, diethylamine,piperazine, tris(hydroxymethyl)aminomethane and tetramethylammoniumhydroxide and basic amino acids such as lysine, arginine andN-methylglutamine.

In addition, compounds of the present invention, or a salt or solvatethereof, may exhibit polymorphism. The present invention alsoencompasses any such polymorphic form.

The compounds of the present invention also contain two or more chiralcenters. For example, the compounds may include P1 cyclopropyl elementof formula

wherein C₁ and C₂ each represent an asymmetric carbon atom at positions1 and 2 of the cyclopropyl ring. Not withstanding other possibleasymmetric centers at other segments of the compounds, the presence ofthese two asymmetric centers means that the compounds can exist asracemic mixtures of diastereomers, such as the diastereomers wherein R₂is configured either syn to the amide or syn to the carbonyl as shownbelow.

The present invention includes both enantiomers and mixtures ofenantiomers such as racemic mixtures.

The enantiomers may be resolved by methods known to those skilled in theart, for example, by formation of diastereoisomeric salts which may beseparated by crystallization, gas-liquid or liquid chromatography,selective reaction of one enantiomer with an enantiomer-specificreagent. It will be appreciated that where the desired enantiomer isconverted into another chemical entity by a separation technique, thenan additional step is required to form the desired enantiomeric form.Alternatively, specific enantiomers may be synthesized by asymmetricsynthesis using optically active reagents, substrates, catalysts orsolvents, or by converting one enantiomer into the other by asymmetrictransformation.

The compounds of the present invention may be in the form of a prodrug.Simple aliphatic or aromatic esters derived from, when present, acidicgroups pendent on the compounds of this invention are preferredprodrugs. In some cases it is desirable to prepare double ester typeprodrugs such as (acyloxy) alkyl esters or (alkoxycarbonyl)oxy)alkylesters.

Certain compounds of the present invention may also exist in differentstable conformational forms which may be separable. Torsional asymmetrydue to restricted rotation about an asymmetric single bond, for examplebecause of steric hindrance or ring strain, may permit separation ofdifferent conformers.

Certain compounds of the present invention may exist in zwitterionicform and the present invention includes each zwitterionic form of thesecompounds and mixtures thereof.

The starting materials useful to synthesize the compounds of the presentinvention are known to those skilled in the art and can be readilymanufactured or are commercially available.

The compounds of the present invention can be manufactured by methodsknown to those skilled in the art, see e.p., U.S. Pat. No. 6,323,180 andUS Patent Appl. 20020111313 A1. The following methods set forth beloware provided for illustrative purposes and are not intended to limit thescope of the claimed invention. It will be recognized that it may bepreferred or necessary to prepare such a compound in which a functionalgroup is protected using a conventional protecting group then to removethe protecting group to provide a compound of the present invention. Thedetails concerning the use of protecting groups in accordance with thepresent invention are known to those skilled in the art.

The compounds of the present invention may, for example, be synthesizedaccording to a general process as illustrated in Scheme I (wherein CPGis a carboxyl protecting group and APG is an amino protecting group):

Briefly, the P1, P2, and P3 can be linked by well known peptide couplingtechniques. The P1, P2, and P3 groups may be linked together in anyorder as long as the final compound corresponds to peptides of theinvention. For example, P3 can be linked to P2-P1; or P1 linked toP3-P2.

Generally, peptides are elongated by deprotecting the α-amino group ofthe N-terminal residue and coupling the unprotected carboxyl group ofthe next suitably N-protected amino acid through a peptide linkage usingthe methods described. This deprotection and coupling procedure isrepeated until the desired sequence is obtained. This coupling can beperformed with the constituent amino acids in stepwise fashion, asdepicted in Scheme I.

Coupling between two amino acids, an amino acid and a peptide, or twopeptide fragments can be carried out using standard coupling proceduressuch as the azide method, mixed carbonic-carboxylic acid anhydride(isobutyl chloroformate) method, carbodiimide (dicyclohexylcarbodiimide,diisopropylcarbodiimide, or water-soluble carbodiimide) method, activeester (ρ-nitrophenyl ester, N-hydroxysuccinic imido ester) method,Woodward reagent K-method, carbonyldiimidazole method, phosphorusreagents or oxidation-reduction methods. Some of these methods(especially the carbodiimide method) can be enhanced by adding1-hydroxybenzotriazole or 4-DMAP. These coupling reactions can beperformed in either solution (liquid phase) or solid phase.

More explicitly, the coupling step involves the dehydrative coupling ofa free carboxyl of one reactant with the free amino group of the otherreactant in the present of a coupling agent to form a linking amidebond. Descriptions of such coupling agents are found in generaltextbooks on peptide chemistry, for example, M. Bodanszky, “PeptideChemistry”, 2^(nd) rev ed., Springer-Verlag, Berlin, Germany, (1993).Examples of suitable coupling agents are N,N′-dicyclohexylcarbodiimide,1-hydroxybenzotriazole in the presence of N,N′-dicyclohexylcarbodiimideor N-ethyl-N′-[(3-dimethylamino)propyl]carbodiimide. A practical anduseful coupling agent is the commercially available(benzotriazol-1-yloxy)tris-(dimethylamino)phosphoniumhexafluorophosphate, either by itself or in the present of1-hydroxybenzotriazole or 4-DMAP. Another practical and useful couplingagent is commercially available 2-(1H-benzotriazol-1-yl)-N, N,N′,N′-tetramethyluronium tetrafluoroborate. Still another practical anduseful coupling agent is commercially availableO-(7-azabenzotrizol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate. The coupling reaction is conducted in an inertsolvent, e.g. dichloromethane, acetonitrile or dimethylformamide. Anexcess of a tertiary amine, e.g. diisopropylethylamine,N-methylmorpholine, N-methylpyrrolidine or 4-DMAP is added to maintainthe reaction mixture at a pH of about 8. The reaction temperatureusually ranges between 0° C. and 50° C. and the reaction time usuallyranges between 15 min and 24 h.

The functional groups of the constituent amino acids generally must beprotected during the coupling reactions to avoid formation of undesiredbonds. Protecting groups that can be used are listed, for example, inGreene, “Protective Groups in Organic Chemistry”, John Wiley & Sons, NewYork (1981) and “The Peptides: Analysis, Synthesis, Biology”, Vol. 3,Academic Press, New York (1981), the disclosures of which are herebyincorporated by reference.

The α-amino group of each amino acid to be coupled to the growingpeptide chain must be protected (APG). Any protecting group known in theart can be used. Examples of such groups include: 1) acyl groups such asformyl, trifluoroacetyl, phthalyl, and ρ-toluenesulfonyl; 2) aromaticcarbamate groups such as benzyloxycarbonyl (Cbz or Z) and substitutedbensyloxycarbonyls, and 9-fluorenylmethyloxycarbonyl (Fmoc); 3)aliphatic carbamate groups such as tert-butyloxycarbonyl (Boc),ethoxycarbonyl, diisopropylmethoxycarbonyl, and allyloxycarbonyl; 4)cyclic alkyl carbamate groups such as cyclopentyloxycarbonyl andadamantyloxycarbonyl; 5) alkyl groups such as triphenylmethyl andbenzyl; 6)trialkylsilyl such as trimethylsilyl; and 7) thiol containinggroups such as phenylthiocarbonyl and dithiasuccinoyl. The preferredα-amino protecting group is either Boc or Fmoc. Many amino acidderivatives suitably protected for peptide synthesis are commerciallyavailable. The α-amino protecting group of the newly added amino acidresidue is cleaved prior to the coupling of the next amino acid. Whenthe Boc group is used, the methods of choice are trifluoroacetic acid,neat or in dichloromethane, or HCl in dioxane or in ethyl acetate. Theresulting ammonium salt is then neutralized either prior to the couplingor in situ with basic solutions such as aqueous buffers, or tertiaryamines in dichloromethane or acetonitrile or dimethylformamide. When theFmoc group is used, the reagents of choice are piperidine or substitutedpiperidine in dimethylformamide, but any secondary amine can be used.The deprotection is carried out at a temperature between 0° C. and roomtemperature (rt or RT) usually 20-22° C.

Any of the amino acids having side chain functionalities must beprotected during the preparation of the peptide using any of theabove-described groups. Those skilled in the art will appreciate thatthe selection and use of appropriate protecting groups for these sidechain functionalities depend upon the amino acid and presence of otherprotecting groups in the peptide. The selection of such protectinggroups is important in that the group must not be removed during thedeprotection and coupling of the α-amino group.

For example, when Boc is used as the α-amino protecting group, thefollowing side chain protecting group are suitable: p-toluenesulfonyl(tosyl) moieties can be used to protect the amino side chain of aminoacids such as Lys and Arg; acetamidomethyl, benzyl (Bn), ortert-butylsulfonyl moieties can be used to protect the sulfidecontaining side chain of cysteine; benzyl (Bn) ethers can be used toprotect the hydroxy containing side chains of serine, threonine orhydroxyproline; and benzyl esters can be used to protect the carboxycontaining side chains of aspartic acid and glutamic acid.

When Fmoc is chosen for the α-amine protection, usually tert-butyl basedprotecting groups are acceptable. For instance, Boc can be used forlysine and arginine, tert-butyl ether for serine, threonine andhydroxyproline, and tert-butyl ester for aspartic acid and glutamicacid. Triphenylmethyl (Trityl) moiety can be used to protect the sulfidecontaining side chain of cysteine.

Once the elongation of the peptide is completed all of the protectinggroups are removed. When a liquid phase synthesis is used, theprotecting groups are removed in whatever manner is dictated by thechoice of protecting groups. These procedures are well known to thoseskilled in the art.

Further, the following guidance may be followed in the preparation ofcompounds of the present invention. For example, to form a compoundwhere R₄—C(O)—, R₄—S(O)₂, a protected P3 or the whole peptide or apeptide segment is coupled to an appropriate acyl chloride or sulfonylchloride respectively, that is either commercially available or forwhich the synthesis is well known in the art. In preparing a compoundwhere R₄O—C(O)—, a protected P3 or the whole peptide or a peptidesegment is coupled to an appropriate chloroformate that is eithercommercially available or for which the synthesis is well known in theart. For Boc-derivatives (Boc)₂O is used.

For example:

Cyclopentanol is treated with phosgene to furnish the correspondingchloroformate.

The chloroformate is treated with the desired NH₂-tripeptide in thepresence of a base such as triethylamine to afford thecyclopentylcarbamate.

In preparing a compound where R₄—N(R₅)—C(O)—, or R₄—NH—C(S)—, aprotected P3 or the whole peptide or a peptide segment is treated withphosgene followed by amine as described in Syn Lett. February 1995; (2);142-144 or is reacted with the commercially available isocyanate and asuitable base such as triethylamine.

In preparing a compound where R₄—N(R₅)—S(O₂), a protected P3 or thewhole peptide or a peptide segment is treated with either a freshlyprepared or commercially available sulfamyl chloride followed by amineas described in patent Ger. Offen. (1998), 84 pp. DE 19802350 or WO98/32748.

The α-carboxyl group of the C-terminal residue is usually protected asan ester (CPG) that can be cleaved to give the carboxylic acid.Protecting groups that can be used include: 1) alkyl esters such asmethyl, trimethylsilylethyl and t-butyl, 2) aralkyl esters such asbenzyl and substituted benzyl, or 3) esters that can be cleaved by mildbase treatment or mild reductive means such as trichloroethyl andphenacyl esters.

The resulting α-carboxylic acid (resulting from cleavage by mild acid,mild base treatment or mild reductive means) is coupled with a R₁SO₂NH₂[prepared by treatment of R₁SO₂Cl in ammonia saturated tetrahydrofuransolution] in the presence of peptide coupling agent such as CDI or EDACin the presence of a base such as 4-dimethylaminopyridine (4-DMAP)and/or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) to incorporate the P1′moiety, effectively assembling the tripeptide P1′-P1-P2-P3-APG.Typically, in this process, 1-5 equivalents of P1′ coupling agents areused.

Furthermore, if the P3 protecting group APG is removed and replaced witha B moiety by the methods described above, and the resultingα-carboxylic acid resulting from cleavage (resulting from cleavage bymild acid, mild base treatment or mild reductive means) is coupled witha R₁SO₂NH₂ [prepared by treatment of R₁SO₂Cl in ammonia saturatedtetrahydrofuran solution or alternative methods described herein] in thepresence of peptide coupling agent such as CDI or EDAC in the presenceof a base such as 4-dimethylaminopyridine (4-DMAP) and/or1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) to incorporate the P1′ moiety,the tripeptide P1′-P1-P2-P3-B is prepared. Typically, in this process,1-5 equivalents of P1′ coupling agents are used.

Compounds of the present invention can be prepared by many methodsincluding those described in the examples, below, and as described inU.S. Pat. No. 6,323,180 and U.S. patent application Ser. No. 10/001,850filed on Nov. 20, 2001. The teachings of U.S. Pat. No. 6,323,180 andU.S. patent application Ser. No. 10/001,850 are incorporated herein, intheir entirety, by reference.

Scheme II further shows the general process wherein compounds of FormulaI are constructed by the coupling of tripeptide carboxylic acidintermediate (1) with a P1′ sulfonamide. (It should be noted that thegroups R₆, R₇, R₈, R₉, R₁₀, R₁₁ as shown below represent substituents ofthe heterocyclic system.) Said coupling reaction requires treatment ofcarboxylic acid (1) with a coupling reagent such as carbonyl diimidazolein a solvent such as THF, which can be heated to reflux, followed by theaddition of the formed derivative of (1), to the P1′ sulfonamide, in asolvent such as THF or methylene chloride in the presence of a base suchas DBU.

An alternative process for the construction of compounds of Formula I isshown in Scheme III. Therein the P1′ sulfonamide element is coupled tothe P1 element using the process employed in Scheme 1. The resultingP1-P1′ moiety can then be deprotected at it's amino terminus. In thisgeneral example a Boc protecting group is employed but one skilled inthe art would recognize that a number of suitable amino protectinggroups could be employed in this process. Said Boc protecting group canbe removed using acid such as trifluoroacetic acid in a solvent such asdichloroethane to provide the deprotected amine as the TFA salt. SaidTFA amine salt can be directly employed in the subsequent couplingreaction or as an alternative the TFA amine salt can be first convertedto the HCl amine salt, and this HCl amine salt is used in said couplingreaction as shown in Scheme III. The coupling of said HCl amine salt (3)with the carboxyl terminus a P4-P3-P2 intermediate can be achieved usingcoupling reagents, such as HATU, in solvents such as dichloromethane toprovide compounds of Formula I (4).

An alternative process for the construction of compounds of Formula I isshown in Scheme IV. Herein the hydrochloride salt of the P1-P1′ terminalamine (1) is coupled to the free carboxyl group of the P2 element usingcoupling agents such as PyBOP, in the presence of a base such asdiisopropyl amine, and in a solvent such as methylene chloride. Theresulting P2-P1-P1′ intermediate can be converted to compounds ofFormula I in a two step process wherein the first step is deprotectionof the P2 amine terminus using an acid such as TFA in a solvent such asmethylene chloride. The resulting trifluoroacetic acid salt can becoupled with the carboxyl terminus of the P4-P3 element using standardcoupling agents such as PyBop in the presence of base such asdiisopropyl amine, and using solvents such methylene chloride to providecompounds of Formula I (4).

The P4-P3-P2 intermediate utilized in the above schemes can beconstructed as previously described with a further description of thisprocess shown in general Scheme V. Therein the free carboxyl terminus ofthe P4-P3 intermediate (1), can be coupled to the amino terminus of theP2 element to provide the P4-P3-P2 dipeptide (2). The carboxyl terminusof the P4-P3-P2 intermediate can be deprotected by saponification of theester group to provide P4-P3-P2 as the free carboxylic acid (3).Intermediates like (3) can be converted to compounds of Formula I usingthe methods described herein.

Compounds of Formula 1 can also be converted into other compounds ofFormula I as described herein. An example of such a process is shown inScheme VI wherein a compound of Formula I (1) which bears a Boc group atthe P4 position is converted in a compound of Formula I (3) wherein saidcompound bears a urea group at the P4 position. The conversion of (1) to(3) can be carried out in a two step process the first of which is theconversion of (1) to amine (2) by treatment of (1) with an acid such asTFA in a solvent such as methylene chloride. The resulting amine TFAsalt can be treated with an isocyanate in the presence of one equivalentof base to provide a compound of Formula I (3) wherein the P3 moiety iscapped with a urea. As previously noted one skilled in the art willrecognize that intermediate (2) can be used as starting materials forthe preparation of compounds of Formula I wherein the P3 group is cappedwith an amide or a sulfonamide, or thiourea, or a sulfamide. Theconstruction of said compounds of Formula I can be achieved usingstandard conditions for the formation of said P4 functionalities fromamines.

In the construction of compounds of Formula I, the P1′ terminus isincorporated into the molecules using one of the general processesoutlined above and described in more detail below. In some examples theP1′ elements, that is the cycloalkyl- or alkyl sulfonamides arecommercially available or can be prepared from the corresponding alkyl-or cycloalkyl-sulfonyl chloride by treating said sulfonyl chloride withammonia. Alternatively, these sulfonamides can be synthesized using thegeneral process outline in Scheme VII. Therein commercially available3-chloro-propylsulfonyl chloride (1) is converted to a suitableprotected sulfonamide as for example by treatment with tert-butyl amine.The sulfonamide obtained (2) is then converted to the correspondingcycloalkylsulfonamide by treatment with two equivalents of a base suchas butyl lithium in a solvent such as THF at low temperature. Theresulting cycloalkylsulfonamide can be deprotected by treatment with anacid to provide the desired unprotected cycloalkylsulfoamide.

The P1 elements utilized in generating compounds of Formula I are insome cases commercially available, but are otherwise synthesized usingthe methods described herein and subsequently incorporated intocompounds of Formula I using the methods described herein. Thesubstituted P1 cyclopropylamino acids can be synthesized following thegeneral process outline in Scheme VIII.

Treatment of commercially available or easily synthesized imine (1) with1,4-dihalobutene (2) in presence of a base produces, provides theresulting imine (3). Acid hydrolysis of 3 then provides 4, which has anallyl substituent syn to the carboxyl group as a major product. Theamine moiety of 4 can protected using a Boc group to provide the fullyprotected amino acid 5. This intermediate is a racemate which can beresolved by an enzymatic process wherein the ester moiety of 5 iscleaved by a protease to provide the corresponding carboxylic acid.Without being bound to any particular theory, it is believed that thisreaction is selective in that one of the enantiomers undergoes thereaction at a much greater rate than its mirror image providing for akinetic resolution of the intermediate racemate. In the examples citedherein, the more preferred stereoisomer for integration into compoundsof Formula I is 5a which houses the (1R,2S) stereochemistry. In thepresence of the enzyme, this enantiomer does not undergo ester cleavageand thereby this enantiomer 5a is recovered from the reaction mixture.However, the less preferred enantiomer, 5b with houses the (1S,2R)stereochemistry undergoes ester cleavage, i.e., hydrolysis, to providethe free acid 6. Upon completion of this reaction, the ester 5a can beseparated from the acid product 6 by routine methods such as, forexample, aqueous extraction methods or chromotography.

Procedures for making P2 intermediates and compounds of Formula I areshown in the Schemes below. It should be noted that in many casesreactions are depicted for only one position of an intermediate.However, it is to be understood that such reactions could be used toimpart modifications to other positions within this intermediate.Moreover, said intermediates, reaction conditions and methods given inthe specific examples are broadly applicable to compounds with othersubstitution patterns. The general Schemes outlined below are followedwith examples herein. Both general and specific examples arenon-limiting, as for example the isoquinoline nucleus is shown as partof the general scheme, Scheme IX, however, this pathway represents aviable process for the construction of alternate heterocyclesubstituents as replacements for the isoquinoline element, such asquinolines, or pyridines.

Scheme IX shows the coupling of an N-protected C4-hydroxyproline moietywith a heterocycle to form intermediate (4) and the subsequentmodification of said intermediate (4) to a compound of Formula I by theprocess of peptide elongation as described herein. It should be notedthat in the first step, that is the coupling of the C4-hydroxy prolinegroup with the heteroaryl element, a base is employed. One skilled inthe art would recognized that this coupling can be done using bases suchas potassium tert-butoxide, or sodium hydride, in solvent such as DMF orDMSO or THF. This coupling to the isoquinoline ring system occurs at theC1 position (numbering for isoquinoline ring system shown inintermediate 2 of Scheme IX) and is directed by the chloro group whichis displaced in this process. It should be noted that the alternativeleaving groups can be utilized at this position such as a fluoro asshown in the Scheme. Said fluoro intermediates (3) are available fromthe corresponding chloro compound using literature procedures describedherein. It should also be noted that the position of the leaving group(chloro or fluoro) in a given ring system can vary as shown in Scheme X,wherein the leaving group (fluoro in this example) is in the C6 positionof the isoquinoline ring system of intermediate (2).

It should be further noted that the position of the ring heteroatom(s)in intermediates like (2) of Scheme IX and Scheme X is also variable, asdefined by the term heterocycle described herein. In Scheme Xintermediate (2) can be coupled to a C4 hydroxy proline derivative toprovide the P2 element (3). This C6-substituted isoquinoline derivativecan be converted to compounds of Formula I using the methods describedherein.

An alternative to the method described above for the coupling of theC4-hydroxyproline to aromatics and heteroaromatics, is provided in theMitsunobu reaction as depicted in

step 1 of Scheme XI. In this general reaction Scheme a C4-hydroxyproline derivative is coupled to a quinazoline ring system. Thisreaction makes use of reagents such as triphenylphosphine and DEAD(diethylazodicarboxylate) in aprotic solvents such as THF or dioxane andcan be used for the formation of aryl and heteroaryl ethers. Note thatin the course of this coupling reaction the stereochemistry of the C4chiral center in the C4-hydroxyproline derivative is inverted andthereby it is necessary to use the C4-hydroxyproline derivative housingthe (S) stereochemistry at the C4 position as starting material. (asshown in Scheme XI). It should be noted that numerous modifications andimprovements of the Mitsunobu reaction have been described in theliterature, the teachings of which are incorporated herein.

In a subset of examples herein, isoquinolines are incorporated into thefinal compounds and specifically into the P2 region of said compounds.One skilled in the art would recognize that a number of general methodsare available for the synthesis of isoquinolines. Moreover, saidisoquinolines generated by these methods can be readily incorporatedinto final compounds of Formula I using the processes described herein.One general methodology for the synthesis of isoquinolines is shown inScheme XII, wherein cinnamic acid derivatives, shown in general form asstructure (2) are

converted to 1-chloroisoquinolines in a four step process. Saidchloroisoquinolines can be subsequently used in coupling reactions toC4-hydroxyproline derivatives as described herein. The conversion ofcinnamic acids to chloroquinolines begins with the treatment of cinnamicacid with an alkylcholorformate in the presence of a base. The resultinganhydride is then treated with sodium azide which results in theformation of an acylazide (3) as shown in the Scheme. Alternate methodsare available for the formation of acylazides from carboxylic acids asfor example said carboxylic acid can be treated withdiphenylphosphorylazide (DPPA) in an aprotic solvent such as methylenechloride in the presence of a base. In the next step of the reactionsequence the acylazide (3) is coverted to the corresponding isoquinolone(4) as shown in the Scheme. In the event the acylazide is heated to atemperature of approximately 190 degrees celcius in a high boilingsolvent such a diphenylmethane.

This reaction is general and provides moderate to good yields ofsubstituted isoquinolone from the corresponding cinnamic acidderivatives. It should noted that said cinnamic acid derivatives areavailable commercially or can be obtained from the correspondingbenzaldehyde (1) derivative by direct condensation with malonic acid orderivatives thereof and also by employing a Wittig reaction. Theintermediate isoquinolones (4) of Scheme XII can be converted to thecorresponding 1-chloroisoquinoline by treatment with phosphorousoxychloride. This reaction is general and can be applied to any of theisoquinolones, quinolones or additional heterocycles as shown herein tocovert a hydroxy substituent to the corresponding chloro compound whensaid hydroxy is in conjugation with a nitrogen atom in said heterocylicring systems.

An alternative method for the synthesis of the isoquinoline ring systemis the Pomeranz-Fritsh procedure. This general method is outlined inScheme XIII. The process begins with the conversion of a benzaldehydederivative (1) to a functionalized imine (2). Said imine is thenconverted to the isoquinoline ring system by treatment with acid atelevated

temperature. This isoquinoline synthesis of Scheme XIII is general, andit should be noted that this process is particularly useful in procuringisoquinoline intermediates that are substituted at the C8 position(note: in intermediate (3) of Scheme XIII the C8 position of theisoquinoline ring is substituted with substituent R₁₁). The intermediateisoquinolines (3) can be converted to the corresponding1-chloroquinolines (5) in a two step process as shown. The first step inthis sequence is the formation of the isoquinoline N-oxide (4) bytreatment of isoquinoline (3) with meta-chloroperbenzoic acid in anaprotic solvent such as dichloromethane. Intermediate (4) can beconverted to the corresponding 1-chloroquinoline by treatment withphosphorous oxychloride in refluxing chloroform. Note this two stepprocess is general and can be employed to procure chloroisoquinolinesand chloroquinolines from the corresponding isoquinolines and quinolinesrespectively.

Another method for the synthesis of the isoquinoline ring system isshown in Scheme XIV. In this process an ortho-alkylbenzamide derivative(1) is treated with a strong

base such as tert-butyl lithium in a solvent such as THF at lowtemperature. To this reaction mixture is then added a nitrilederivative, which undergoes an addition reaction with the anion derivedfrom deprotonation of (1), resulting in the formation of (2). Thisreaction is general and can be used for the formation of substitutedisoquinolines. Intermediate (2) of Scheme XIV can be converted to thecorresponding 1-chloroquinoline by the methods described herein.

An additional method for the synthesis of isoquinolines is shown inScheme XV.

The deprotonation of intermediate (1) using tert-butyl lithium isdescribed above. In the present method however, said intermediate anionis trapped by an ester, resulting in the formation of intermediate (2)as shown below. In a subsequent reaction ketone (2) is condensed withammonium acetate at elevated temperature providing for the formation ofquinolone (3). This reaction is general and can be applied for theconstruction of substituted isoquinolones which can then be converted tothe corresponding 1-chloroisoquinolines as described herein.

Yet an additional method for the construction of isoquinolines is foundin Scheme XVI. In the first step of this process an ortho-alkylaryliminederivatives such as (1) is subjected to deprotonation conditions(sec-butyl lithium, THF) and the resulting anion is quenched by

the addition of an activated carboxylic acid derivative such as aWeinreb amide. The resulting keto imine (2) can be converted to thecorresponding isoquinoline by condensation with ammonium acetate atelevated temperatures. This method is general and can be used for thesynthesis of substituted isoquinolines. Said isoquinolines can beconverted to the corresponding 1-chloroquinoline by the methodsdescribed herein.

The heterocycles described herein, and which are incorporated into thecompounds of Formula I can be further functionalized. It is obvious toone skilled in the art that additional functionalization of saidheterocycles can be done either before or after incorporation of thesefunctionalities into compounds of Formula I. The following Schemesillustrate this point. For example Scheme XVII shows the conversion of a1-chloro-

6-fluoro-isoquinoline to the corresponding1-chloro-6-alkoxy-isoquinoline species, by treatment of (1) of (eq. 1)with a sodium or potassium alkoxide species in the alcohol solvent fromwhich the alkoxide is derived at room temperature. In some cases it maybe necessary to heat the reaction to drive it to completion. Saidchloroquinoline can be incorporated into a compound of Formula I usingthe art described herein. Modifications of a P2 heterocyclic element canalso be done after it's incorporation into compounds of Formula I asshown in (eq. 2) of Scheme VXII. Specifically compounds such as (1) in(eq. 2) which contain a leaving group in the pthalazine nucleus can bedisplaced by a nucleophile such as an alkoxide in solvents such as thecorresponding alcohol from which the alkoxide is derived. These reactionscan be conducted at room temperature but in some cases it may benecessary to heat the reaction to drive it to completion.

Scheme XVIII provides a general example for the modification ofheterocycles as defined herein by employing palladium mediated couplingreactions. Said couplings can be employed to functionalize a heterocycleat each position of the ring system providing said ring is suitablyactivated or functionalized, as for example with a chloride as shown inthe Scheme. This sequence begins with 1-chloroisoquinoline (1) whichupon treatment with metachloroperbenzoic acid can be converted to thecorresponding N-oxide (2). Said intermediate (2) can be converted to thecorresponding 1,3-dichloroisoquinoline (3) by treatment with phosphorousoxychloride in refluxing chloroform. Intermediate (3) can be coupledwith N-Boc-4-hydroxyproline by the methods described herein to provideintermediate (5) as shown in the Scheme. Intermediate (5) can undergo aSuzuki coupling with an aryl boronic acid, in the presence of apalladium reagent and base, and in a solvent such as THF or toluene orDMF to provide the C3-arylisoquinoline intermediate (6).Heteroarylboronic acids can also be employed in this Pd mediatedcoupling process to provide C3-heteroarylisoquinolines. Intermediate (6)can be converted into final compounds of Formula I by the methodsdescribed herein.

Palladium mediated couplings of heteroaryl systems with aryl orheteroaryl elements can also be employed at a later synthetic stage inthe construction of compounds of Formula I as shown in Scheme DOC.Therein tripeptide acylsulfonamide intermediate (1) is coupled to a1-chloro-3-bromoisoquinoline (2) using the previously described processof alkoxide displacement of an heteroarylhalo moiety to provideintermediate (3). The coupling of (1) and (2) is most efficient in thepresence of a catalyst such as lanthanum chloride as described herein.The isoquinoline ring system of intermediate (3) can be furtherfunctionalized by employing either Suzuki couplings (Process 1:subjecting (3) to heteroaryl or aryl boronic acids in the presence of apalladium catalyst such as palladium tetra(triphenylphosphine) and abase such as cesium carbonate in solvents such as DMF) or Stillecouplings (Process 2: subjecting (3) to heteraryl or aryl tinderivatives in the presence of palladium catalyst such as palladiumtetra(triphenylphosphine in solvents such as toluene).

Palladium reactions can also be employed to couple C4-amino prolineelements with functionalized heterocycles. Scheme XX shows intermediate(1) coupling with a functionalized isoquinoline in the presence of apalladium catalyst and a base in a solvent such as toluene.Intermediates like (3) can be converted to compounds of Formula I usingthe methods described herein.

The construction of functionalized isoquinoline ring systems is alsopossible employing [4+2] cycloaddition reactions. For example (SchemeXXI) the use of vinyl isocyantes (1) in cycloaddition reactions withbenzyne precursors (2) provides functionalized isoquinolones (3). Saidisoquinolines can be incorporated into compounds of Formula I using themethods described herein.

Method A Step 1

Glycine ethyl ester hydrochloride (303.8 g, 2.16 mole) was suspended intert-butylmethyl ether (1.6 L). Benzaldehyde (231 g, 2.16 mole) andanhydrous sodium sulfate (154.6 g, 1.09 mole) were added and the mixturecooled to 0° C. using an ice-water bath. Triethylamine (455 mL, 3.26mole) was added dropwise over 30 min and the mixture stirred for 48 h atrt. The reaction was then quenched by addition of ice-cold water (1 L)and the organic layer was separated. The aqueous phase was extractedwith tert-butylmethyl ether (0.5 L) and the combined organic phaseswashed with a mixture of saturated aqueous NaHCO₃ (1 L) and brine (1 L).The solution was dried over MgSO₄, concentrated in vacuo to afford 392.4g of the N-benzyl imine product as a thick yellow oil that was useddirectly in the next step. ¹H NMR (CDCl₃, 300 MHz) δ 1.32 (t, J=7.1 Hz,3H), 4.24 (q, J=7.1 Hz, 2H), 4.41 (d, J=1.1 Hz, 2H), 7.39-7.47 (m, 3H),7.78-7.81 (m, 2H), 8.31 (s, 1H).

Alternate Route for the Preparation of RacemicN-Boc-1-amino-2-vinylcyclopropane carboxylic acid ethyl esterhydrochloride

To a solution of potassium tert-butoxide (11.55 g, 102.9 mmol) in THF(450 mL) at −78° C. was added the commercially available N,N-dibenzylimine of glycine ethyl ester (25.0 g, 93.53 mmol) in THF (112 mL). Thereaction mixture was warmed to 0° C., stirred for 40 min, and was thencooled back to −78° C. To this solution was addedtrans-1,4-dibromo-2-butene (20.0 g, 93.50 mmol), the mixture stirred for1 h at 0° C. and was cooled back to −78° C. Potassium tert-butoxide(11.55 g, 102.9 mmol) was added, the mixture immediately warmed to 0°C., and was stirred one more hour before concentrating in vacuo. Thecrude product was taken up in Et₂O (530 mL), 1N aq. HCl solution (106mL, 106 mmol) added and the resulting biphasic mixture stirred for 3.5 hat rt.

Example 184 General Procedure for Alkylation with the Tripeptide(Compound 184) and P2* General Scheme Preparation of Example 184Compound 184

The preparation of the tripeptide component, Example 184 was achieved bya sequential amide coupling using HATU as the coupling agent. It isunderstood that many standard coupling agents could be employed for thefollowing scheme.

Preparation of Intermediate Example 184a

To a mixture of HATU (820 mg, 2.2 mmol), Example 180a(Boc-4R-hydroxyproline, 417 mg, 1.8 mmol) and Example 180c(cyclopropanesulfonic acid(1(R)-amino-2(S)-vinyl-cyclopropanecarbonyl)-amide hydrochloride salt,490 mg, 1.8 mmol) in a flame dried flask at room temperature was addeddry CH₂Cl₂ (8 mL). The mixture was kept under dry N₂ before it waschilled to −78° C. Hunig's base (diisopropylethylamine, 625 μL, 3.6mmol) was added slowly over a period 5 min and the mixture turned into apale orange suspension. Stirring was continued for an hour whiletemperature was allow to raise to ambient. LC/MS showed completeconversion into the desired product 184a. The crude reaction was workedup as usual, washed with three portions (5 mL) of water, organicresidues were extracted into ethyl acetate (3×5 mL). The crude productwas obtained by removal of organic solvents in vacuo. The material wasused in the next step without further purification.

Preparation of Intermediate Example 184b

The dried solid from the previous step was taken into 9 mL of CH₂Cl₂ atroom temperature. To this solution was added 3 mL of trifluoroaceticacid forming a pale yellowish solution. Stirring was continued for 2hours at room temperature. LC/MS showed no starting material 184a whilethe desired product 184b was the major signal along with a signalcorresponding to a side product carried over from HATU in the stepearlier. The solvents were evaporated and the solid residue was used inthe next step immediately without further purification.

Preparation of the Tripeptide, Compound 184

BOCNH-P3(L-tert-BuGly)-P2[(4R)-hydroxy-S-proline]-P1(1R,2S VinylAcca)-CONHSO₂-Cyclopropane [Notebook 46877-128]

The crude product from the previous step (Example 184b, 1.8 mmol) wasmixed with HATU (700 mg, 1.8 mmol) and BOC-L-tert-leucine (Example 180f,Fluka Chemicals, 420 mg, 1.8 mmol) in CH₂Cl₂ (10 mL) at roomtemperature. To this suspension was treated Hünig's base (1 mL, excess)forming a somewhat thinner, orange suspension. LC/MS showed someconversion into compound 184. Complete conversion into the desiredproduct 184 was observed after stirring was continued for two days atroom temperature. Crude reaction mixture was evaporated to dryness. Theresidue was taken into ethyl acetate. Most of HATU residue was removedby extractions with half saturated, freshly prepared sodium bicarbonatesolution. The last traces of HATU residue (1-hydroxy 7-azabenzotriazole)was removed by washing with deionized water. Evaporation of solventsgave 990 mg (98%) of the desired product as white foam. This material issuitable for the subsequent alkylation with electrophiles such asquinolines and isoquinolines directly without further purification.LC/MS R_(t)-min (MNa⁺) [method A]: 2.65 (579). ¹H NMR (400 MHz, CD₃OD) δppm 0.95 (s, 2H) 0.99 (s, 9H) 1.05 (m, 2H) 1.21 (m, 1H) 1.39 (m, 9H)1.84 (dd, J=8.31, 5.38 Hz, 1H) 1.96 (m, 1H) 2.11 (m, 1H) 2.20 (m, 1H)2.91 (m, 1H) 3.80 (m, 2H) 4.28 (d, J=9.78 Hz, 1H) 4.35 (dd, J=9.90, 6.97Hz, 1H) 4.47 (s, 1H) 5.11 (m, 1H) 5.29 (d, J=17.12 Hz, 1H) 5.75 (m, 1H).

Alkylation of the Tripeptide (Compound 184) with Electrophiles:

To a flame-dried 25 mL round bottom flask was charged with Compound 184,(0.5-1.0 mmol), substituted 4-chloroquinoline (1.0 equivalent) andlanthanum chloride (LaCl₃ anhydrous beads, used as supplied by Aldrich,M. W. 245 g/mol; 1.0 equivalent. Note: the inclusion of such additivewas found to be helpful in some cases especially with those lessreactive electrophiles. This reagent can, at times, be omitted if theelectrophiles are sufficiently reactive towards anionic alkylation) in 2mL dry DMF. The inorganic salt was only sparingly soluble in DMF at roomtemperature. The mixture was chilled to −78° C. (dry-ice/acetone bath)with stirring under nitrogen. To this chilled mixture was added a THFsolution of potassium tert-butoxide (1.0 M, used as supplied by Aldrich,5.5 equivalents) and the color of mixture changed from colorless to paleyellowish or greenish. It was stirred at −78° C. for a period dependentupon the 4-chloroquinoline reactivity (a few hrs. at −78° C. toovernight at room temperature). The inorganic salt was also found tochange into a fine emulsion at the end. It was quenched with a halfsaturated NH₄Cl aqueous solution (2 mL). Organic materials wereextracted into ethyl acetate (10 mL×3). Organic layers were combined,back washed with deionized water (10 mL×2). Evaporation of the organicfraction gave a crude mixture rich in the desired product as determinedby LC/MS. The desired product was isolated by preparative HPLC usingstandard separation parameters (typically: 3.0×50 mm Xterra column @4min gradient and 4 mL/min flow rate) to give the analytically puredesired product. The alkylation of 1-halo isoquinoline series wascarried out in exactly the same way.

Both 2,3-dihydro-1-oxa-4-aza-cyclopenta[a]naphthalen-5-ol and1-oxa-4-aza cyclopenta[a]naphthalen-5-ol were produced together when theprocedures (references 1 and 2) cited above were followed. Conversion ofthe pair into their chloro derivatives was accomplished by POCl₃ asusual: The crude hydroxy products (about 2 g, pale yellow oil) wastreated with 15 mL of POCl₃ and the mixture was brought to reflux for 3hours. After removal of the POCl₃ in vacuo, the residue was stirred withEtOAc (1 L), and cold aqueous NaOH (220 mL, 1.0 N) for 15 min. Theorganic layer was separated, washed with water (2×200 mL), brine (200mL), and dried over MgSO₄, and concentrated in vacuo to supply 300 mg ofExample 217, 5-chloro-2,3-dihydro-1-oxa-4-aza-cyclopenta[a]naphthalene(13.2%) and 100 mg of Example 218, 5-chloro-1-oxa-4-azacyclopenta[a]naphthalene (4.4%) as light brown solids after silica gelchromatographic separation.

Preparation of5-fluoro-2,3-dihydro-1-oxa-4-aza-cyclopenta[a]naphthalene, and Final P2*Coupling Products

The chloride/fluoride exchange was achieved by the method (reference 3)cited above. Thus 90 mg of5-chloro-2,3-dihydro-1-oxa-4-aza-cyclopenta[a]naphthalene (Example 217)was suspended in 1.5 mL of Bu₄PHF₂ and was irradiated under microwave(Smith Reactor) to about 120° C. for 2 hours. After aqueous work up andcolumn purification, 22 mg of fluoride product was obtained (26.9%).LC/MS rt-min (MH⁺): 1.91 (190) [method B]. The furan derivative (Example218), 5-chloro-1-oxa-4-aza-cyclopenta[a]naphthalene was sufficientlyreactive to be alkylated with the tripeptide directly without fluorideactivation.

Preparation of 3-halo and 3-heteroaryl 4-alkoxy and 4-hydroxyisoquinoline P2* Derivatives

General Synthetic Scheme

4-Methoxy isoquinoline (Example 222a) was prepared from 4-bromoisoquinoline by a novel and convenient procedure using ordinarylaboratory equipments and reagents. A regioselective NBS brominationgave 3-bromo-4-methoxy isoquinoline (Example 222b) in good yields. MCPBAoxidation proceeded uneventfully to furnish the corresponding N-oxide(Example 222c), which was isomerized into 1-chloro-3-bromo-4-methoxyisoquinoline (Example 222d) using the usual POCl₃ procedure. The4-methoxy isoquinoline was alkylated with the tripeptide to give thecorresponding 3-bromo-4-methoxy P2* derivative suitable for Stille andSuzuki coupling. Alternatively the 4-methoxy isoquinoline wasde-methylated in BBr₃ to give the 4-hydroxy-3-bromo-1-chloroisoquinoline (Example 222e). The 4-hydroxy group was re-protected withSEM-chloride to give the 4-SEM protected intermediate Example 222. The4-hydroxy compound was re-generated once the coupling was achieved byeither an acid induced, or a fluoride induced deprotection protocol.

Example 222d Preparation of 1-chloro-3-bromo-4-methoxy isoquinoline Step1

A solution of 4-bromo isoquinoline (15 g, 73 mmol, commercial material)in 200 mL dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (DMPU, Aldrich)was added solid potassium methoxide (5.6 gm, 80 mmol). The reactionvessel was immersed in an oil bath at 105° C. for 20 min. The color ofmixture changed rapidly from its initial very pale to dark greenishbrown immediately after warming. The reaction vessel was removed fromthe oil bath and was diluted with water, the organic residues werepartitioned into ether by multiple extraction with portions of ether.TLC analysis showed two new, spots (1:1 v/v mixture of hexanes and ethylacetate as eluent) of roughly equal size. These were separated onsilica-gel (Merck, type-H) column eluted with straight hexanes, followedby gradual addition of ether into the mobile phase. The desired product,4-methoxy isoquinoline (4.1 gm, 35.3%) was isolated after evaporation ofsolvents. The other product was also isolated as the reductionby-product isoquinoline. The identity of the by-product was confirmed byNMR comparison with authentic material. Example 222a: LC/MS R_(t)-min(MH⁺) [method C]: 1.16 (160). ¹H NMR (400 MHz, CHLOROFORM-D) δ 4.07 (s,3H) 7.61 (m, 1H) 7.69 (m, 1H) 7.93 (d, J=8.07 Hz, 1H) 8.08 (s, 1H) 8.19(d, J=8.56 Hz, 1H) 8.89 (s, 1H). [Note: this compound was previouslyprepared in Zoltewicz, John A.; Oestreich, Terence M.; Sale, Alan A,Journal of the American Chemical Society (1975), 97(20), 5889-96 in a“Monel Bomb”, and later by a “focused microwave” initiated procedure inCherng, Yie-Jia, Tetrahedron (2002), 58(6), 1125-1129. The presentprocedure required neither special high pressure apparatus norpreparative scale microwave equipment].

Step 2

The material (Example 222a) was subjected to NBS bromination, thus4-methoxy isoquinoline (Example 222a, 2.1 gm, 13.2 mmol) in1,2-dichloroethane (DCE, 150 mL) was treated with N-bromosuccinimide(NBS, 1.5 gm, 8.4 mmol, 0.6×) at 70° C. for an hr followed by additionof second portion of 1.5 gm NBS. The dark brownish mixture was stirredfor another hr before the addition of third portion of 1.0 gm NBS. Thebromination was monitored by LC-MS until there was no starting materialleft. The crude mixture was evaporated to dryness and the desiredproduct was filtered over a short bed of silica-gel (Type-H, Merck, 3 cmdiameter by 1.5 cm height) eluted with straight hexanes first followedby gradually increasing the amount of ether. The desired product,(Example 222b), was isolated as an oily material (1.7 gm, 54%). LC/MSR_(t)-min (MH⁺) [method C]: 2.65 (238). ¹H NMR (400 MHz, CHLOROFORM-D) δppm 4.04 (s, 3H) 7.64 (t, J=7.58 Hz, 1H) 7.76 (t, J=7.09 Hz, 1H) 7.99(d, J=8.31 Hz, 1H) 8.11 (d, J=8.31 Hz, 1H) 8.85 (s, 1H).[3-Bromo-4-methoxy isoquinoline was previously prepared by a differentprocedure: Finkentey, Christel; Langhals, Elke; Langhals, Heinz.Chemische Berichte (1983), 116(6), 2394-7. NMR of the product wasidentical to that reported].

Step 3

The product from NBS bromination was subjected to MCPBA oxidation inmethylene chloride at room temperature. Thus MCPBA (1.80 gm, 77% pure,8.0 mmol) was added into a solution of 3-bromo-4-methoxy isoquinoline(Example 222b, 1.65 gm, 6.9 mmol) in 35 mL of CH₂Cl₂. The solution wasstirred for 4 hrs forming a white suspension. Sodium bicarbonatesolution (5%, freshly prepared, 20 mL) was added into the mixture,organic residues were extracted into CH₂Cl₂ (10×25 mL). Multipleextraction in organic solvent was necessary to recover the somewhatwater solution N-oxide product. The crude material obtained afterevaporation of solvents was further purified by a filtration oversilica-gel to give 1.36 gm (5.4 mmol, 78%) of the N-oxide (Example 222c)as a ceraceous solid. LC/MS R_(t)-min (MH⁺) [method C]: 1.79 (254). ¹HNMR (400 MHz, CHLOROFORM-D) δ ppm 4.07 (s, 3H) 7.63 (m, 2H) 7.72 (m, 1H)8.00 (m, 1H) 8.86 (s, 1H).

Step 4

The final N-oxide rearrangement was done as usual in POCl₃ usingprocedure described elsewhere. Yield of Example 222d was essentiallyquantitative. LC/MS R_(t)-min (MH⁺) [method D]: 2.69 (272). ¹H NMR asHCl salt, (400 MHz, CHLOROFORM-D) δ ppm 4.07 (s, 3H) 7.81 (m, 1H) 7.92(m, 1H) 8.17 (d, J=8.31 Hz, 1H) 8.34 (d, J=8.31 Hz, 1H). ¹H NMR as freebase, (400 MHz, CHLOROFORM-D) δ ppm 4.03 (s, 3H) 7.72 (m, 1H) 7.81 (m,1H) 8.12 (d, J=8.56 Hz, 1H) 8.28 (d, J=8.56 Hz, 1H).

The free base (Example 222d) obtained in the previous step was alkylatedwith the tripeptide fragment using the alkylation protocol (Example 184)described elsewhere to give 79% of the desired product as a paper-whitesolid.

Example 224 and 225 Preparation of Compounds 224 and Compound 225

The 4-methoxy group in 1-chloro-3-bromo-4-methoxy isoquinoline (Example222d) described previously was converted into α-trimethylsilyl ethoxymethyl (SEM) moiety by the following procedure.1-Chloro-3-bromo-4-methoxy isoquinoline (Example 222d) was demethylatedusing BBr₃ (final adjusted reaction concentration was 0.2-0.3 MolarBBr₃) at room temperature for 12 hrs. The high BBr₃ concentration forsuch de-methylation was found to be necessary and efficient. The crudereaction mixture was diluted with 50 volumes of anhydrous methanol priorto evaporation to dryness. The demethylation was essentiallyquantitative. Example 222e: LC/MS R_(t)-min (MH⁺) [method D]: 2.32(258). ¹H NMR of free HCl salt (400 MHz, CHLOROFORM-D) δ ppm 5.83 (br.s, 1H) 7.73 (t, J=7.70 Hz, 1H) 7.79 (t, J=7.58 Hz, 1H) 8.22 (m, 2H). The4-hydroxy-3-bromo-1-chloro isoquinoline (Example 222e) was re-protectedwith 2-(trimethylsilyl) ethoxy methyl chloride (SEM-Cl). The crude freebase from the previous preparation was dried to 40 microns (Hg) at roomtemperature prior to re-protection with SEM-chloride. To a solution ofthe 4-hydroxy compound (Example 222e, 1.33 gm, 5.2 mmol) in methylenechloride (50 ml) at 0° C. was added sequentially diisopropylethyl amine(2 mL, 11.5 mmol) and SEM-chloride (1.8 mL, 10 mmol). The mixture wasstirred for 10 min before it was washed with a freshly prepared NaHCO₃solution (5%, 100 mL). The organic residues were extracted into severalportions of methylene chloride, the combined organic layers wereback-washed with 20 mL deionized water before it was concentrated invacuo. The SEM protection was essentially quantitative. Example 222:LC/MS R_(t)-min (MH⁺) [method D]: 3.40 (410). ¹H NMR (400 MHz,CHLOROFORM-D) δ ppm 0.03 (s, 9H) 0.99 (m, 2H) 3.98 (m, 2H) 5.33 (s, 2H)7.72 (m, 1H) 7.80 (m, 1H) 8.17 (d, J=8.56 Hz, 1H) 8.27 (d, J=8.07 Hz,1H). Alkylation of 4-SEM protected isoquinoline with tripeptide:Compound 224 and Compound 225 were generated from the same tripeptidealkylation reaction. The 4-hydroxy compound (Compound 224) was producedmost probably as a result of the TFA present during the preparative HPLCpurification.

General Synthetic Scheme

Example 227 Preparation of Compound 227

6-Chloro-1,3-Oxazino[5,6-c]isoquinoline was prepared by the procedure ofMiyoko Toyama and Hirotaka Otomasu starting from 1-chloro-4-hydroxyisoquinoline. The starting material: 1-chloro-4-hydroxy isoquinoline(Example 226c) was prepared by the synthetic sequence shown above. MCPBAoxidation of 4-methoxy isoquinoline (Example 222a) was carried as usualto give 79.1% of the corresponding N-oxide (Example 226a). The materialwas converted into the 1-chloro derivative immediately afterward inPOCl₃ to give the chloride (Example 226b) in essentially quantitativeyield. The crude 1-chloro-4-methoxy isoquinoline was de-methylated inBBr₃ at room temperature to give the corresponding 1-chloro-4-hydroxyisoquinoline (Example 226c) after treating the crude BBr₃ mixture withanhydrous methanol at room temperature, followed by evaporation to getrid of excess of borate residues. The reaction of Miyoko Toyama andHirotaka Otomasu gave 266 mg of 6-chloro-1,3-oxazino[5,6-c]isoquinoline(Example 226d, 62.3%) overall yield from 300 mg of 4-methoxyisoquinoline in 4 steps.

The chloride was found to be unreactive under the alkylation protocol ofExample 184.

Thereaction was not allowed to go to completion, and the crude reactionmixture was recovered as a mixture of ratio of 1:2.4 (Cl:F). Withoutfurther purification, the chloride/fluoride mixture was alkylated withthe tripeptide using the procedure of Example 184 to give 66 mg (50.0%)ofBOCNH-P3(L-t-BuGly)-P2[(4R)-(1,3-oxazino[5,6-c]isoquinoline-6-oxo)-S-proline]-P1(1R,2SVinylAcca)-CONHSO₂Cyclopropane after preparative HPLC purification.LC/MS R_(t)-min (MNa⁺) [method D]: 3.03 (764). ¹H NMR (400 MHz, CD₃OD) δppm 1.01 (s, 9H) 1.06 (dd, J=8.07, 1.96 Hz, 2H) 1.22 (s, 10H) 1.34 (d,J=6.11 Hz, 1H) 1.42 (m, 1H) 1.86 (dd, J=8.07, 5.38 Hz, 1H) 2.23 (m, 2H)2.59 (dd, J=13.82, 6.97 Hz, 1H) 2.93 (m, 1H) 4.03 (dd, J=11.86, 3.06 Hz,1H) 4.23 (s, 1H) 4.41 (d, J=11.98 Hz, 1H) 4.50 (dd, J=9.66, 6.97 Hz, 1H)4.87 (m, 2H) 5.11 (d, J=10.52 Hz, 1H) 5.28 (d, J=17.12 Hz, 1H) 5.34 (s,2H) 5.74 (m, 2H) 7.51 (t, J=7.46 Hz, 1H) 7.70 (t, J=7.58 Hz, 1H) 7.95(d, J=8.31 Hz, 1H) 8.12 (d, J=8.31 Hz, 1H).

Recombinant HCV NS3/4A Protease Complex FRET Peptide Assay

The purpose of this in vitro assay was to measure the inhibition of HCVNS3 protease complexes, derived from the BMS, H77C or J416S strains, asdescribed below, by compounds of the present invention. This assayprovides an indication of how effective compounds of the presentinvention would be in inhibiting HCV proteolytic activity.

Serum from an HCV-infected patient was obtained from Dr. T. Wright, SanFrancisco Hospital. An engineered full-length cDNA (complimentdeoxyribonucleic acid) template of the HCV genome (BMS strain) wasconstructed from DNA fragments obtained by reverse transcription-PCR(RT-PCR) of serum RNA (ribonucleic acid) and using primers selected onthe basis of homology between other genotype 1a strains. From thedetermination of the entire genome sequence, a genotype 1a was assignedto the HCV isolate according to the classification of Simmonds et al.(See P Simmonds, K A Rose, S Graham, S W Chan, F McOmish, B C Dow, E AFollett, P L Yap and H Marsden, J. Clin. Microbiol., 31(6), 1493-1503(1993)). The amino acid sequence of the nonstructural region, NS2-5B,was shown to be >97% identical to HCV genotype 1a (H77C) and 87%identical to genotype 1b (J4L6S). The infectious clones, H77C (1agenotype) and J4L6S (1b genotype) were obtained from R. Purcell (NIH)and the sequences are published in Genbank (AAB67036, see Yanagi, M.,Purcell, R. H., Emerson, S. U. and Bukh, J. Proc. Natl. Acad. Sci.U.S.A. 94(16), 8738-8743 (1997); AF054247, see Yanagi, M., St Claire,M., Shapiro, M., Emerson, S. U., Purcell, R. H. and Bukh, J, Virology244 (1), 161-172. (1998)).

The BMS, H77C and J4L6S strains were used for production of recombinantNS3/4A protease complexes. DNA encoding the recombinant HCV NS3/4Aprotease complex (amino acids 1027 to 1711) for these strains weremanipulated as described by P. Gallinari et al. (see Gallinari P,Paolini C, Brennan D, Nardi C, Steinkuhler C, De Francesco R.Biochemistry. 38(17):5620-32, (1999)). Briefly, a three-lysinesolubilizing tail was added at the 3′-end of the NS4A coding region. Thecysteine in the P1 position of the NS4A-NS4B cleavage site (amino acid1711) was changed to a glycine to avoid the proteolytic cleavage of thelysine tag. Furthermore, a cysteine to serine mutation was introduced byPCR at amino acid position 1454 to prevent the autolytic cleavage in theNS3 helicase domain. The variant DNA fragment was cloned in the pET21bbacterial expression vector (Novagen) and the NS3/4A complex wasexpressed in Escherichia. coli strain BL21 (DE3) (Invitrogen) followingthe protocol described by P. Gallinari et al. (see Gallinari P, BrennanD, Nardi C, Brunetti M, Tomei L, Steinkuhler C, De Francesco R., JVirol. 72(8):6758-69 (1998)) with modifications. Briefly, NS3/4Aexpression was induced with 0.5 mM Isopropyl β-D-1-thiogalactopyranoside(IPTG) for 22 hr at 20° C. A typical fermentation (10 L) yieldedapproximately 80 g of wet cell paste. The cells were resuspended inlysis buffer (10 mL/g) consisting of 25 mMN-(2-Hydroxyethyl)Piperazine-N′-(2-Ethane Sulfonic acid) (HEPES), pH7.5,20% glycerol, 500 mM Sodium Chloride (NaCl), 0.5% Triton-X100, 1 ug/mllysozyme, 5 mM Magnesium Chloride (MgCl₂), 1 ug/ml DnaseI, 5 mMβ-Mercaptoethanol (βME), Protease inhibitor—Ethylenediamine Tetraaceticacid (EDTA) free (Roche), homogenized and incubated for 20 mins at 4° C.The homogenate was sonicated and clarified by ultra-centrifugation at235000 g for 1 hr at 4° C. Imidazole was added to the supernatant to afinal concentration of 15 mM and the pH adjusted to 8.0. The crudeprotein extract was loaded on a Nickel-Nitrilotriacetic acid (Ni-NTA)column pre-equilibrated with buffer B (25 mM HEPES, pH8.0, 20% glycerol,500 mM NaCl, 0.5% Triton-X100, 15 mM imidazole, 5 mM βME). The samplewas loaded at a flow rate of 1 mL/min. The column was washed with 15column volumes of buffer C (same as buffer B except with 0.2%Triton-X100). The protein was eluted with 5 column volumes of buffer D(same as buffer C except with 200 mM Imidazole).

NS3/4A protease complex-containing fractions were pooled and loaded on adesalting column Superdex-S200 pre-equilibrated with buffer D (25 mMHEPES, pH7.5, 20% glycerol, 300 mM NaCl, 0.2% Triton-X100, 10 mM βME).Sample was loaded at a flow rate of 1 mL/min. NS3/4A proteasecomplex-containing fractions were pooled and concentrated toapproximately 0.5 mg/ml. The purity of the NS3/4A protease complexes,derived from the BMS, H77C and J4L6S strains, were judged to be greaterthan 90% by SDS-PAGE and mass spectrometry analyses.

The enzyme was stored at −80° C., thawed on ice and diluted prior to usein assay buffer. The substrate used for the NS3/4A protease assay wasRET S1 (Resonance Energy Transfer Depsipeptide Substrate; AnaSpec, Inc.cat #22991)(FRET peptide), described by Taliani et al. in Anal. Biochem.240(2):60-67 (1996). The sequence of this peptide is loosely based onthe NS4A/NS4B natural cleavage site except there is an ester linkagerather than an amide bond at the cleavage site. The peptide substratewas incubated with one of the three recombinant NS3/4A complexes, in theabsence or presence of a compound of the present invention, and theformation of fluorescent reaction product was followed in real timeusing a Cytofluor Series 4000.

The reagents were as follow: HEPES and Glycerol (Ultrapure) wereobtained from GIBCO-BRL. Dimethyl Sulfoxide (DMSO) was obtained fromSigma. β-Mercaptoethanol was obtained from Bio Rad.

Assay buffer: 50 mM HEPES, pH7.5; 0.15M NaCl; 0.1% Triton; 15% Glycerol;10 mM βME. Substrate: 2 μM final concentration (from a 2 mM stocksolution in DMSO stored at −20° C.). HCV NS3/4A type 1a (1b), 2-3 nMfinal concentration (from a 5 μM stock solution in 25 mM HEPES, pH7.5,20% glycerol, 300 mM NaCl, 0.2% Triton-X100, 10 mM βME).

The assay was performed in a 96-well polystyrene black plate fromFalcon. Each well contained 25 μl NS3/4A protease complex in assaybuffer, 50 μl of a compound of the present invention in 10% DMSO/assaybuffer and 25 μl substrate in assay buffer. A control (no compound) wasalso prepared on the same assay plate. The enzyme complex was mixed withcompound or control solution for 1 min before initiating the enzymaticreaction by the addition of substrate. The assay plate was readimmediately using the Cytofluor Series 4000 (Perspective Biosystems).The instrument was set to read an emission of 340 nm and excitation of490 nm at 25° C. Reactions were generally followed for approximately 15minutes.

The percent inhibition was calculated with the following equation:100−[(δF _(inh) /δF _(con))×100]where δF of is the change in fluorescence over the linear range of thecurve. A non-linear curve fit was applied to theinhibition-concentration data, and the 50% effective concentration(IC₅₀) was calculated by the use of Excel Xl-fit software using theequation, y=A+((B−A)/(1+((C/x)^D))).

All of the compounds tested were found to have IC50s of 10 μM or less.Further, compounds of the present invention, which were tested againstmore than one type of NS3/4A complex, were found to have similarinhibitory properties though the compounds uniformly demonstratedgreater potency against the 1b strains as compared to the 1a strains.

Specificity Assays

The specificity assays were performed to demonstrate the selectivity ofthe compounds of the present invention in inhibiting HCV NS3/4A proteaseas compared to other serine or cysteine proteases.

The specificities of compounds of the present invention were determinedagainst a variety of serine proteases: human leukocyte elastase (HLE),porcine pancreatic elastase (PPE) and human pancreatic chymotrypsin andone cysteine protease: human liver cathepsin B. In all cases a 96-wellplate format protocol using colorimetric p-nitroaniline (pNA) substratespecific for each enzyme was used as described previously (Patent WO00/09543) with some modifications to the serine protease assays. Allenzymes were purchased from Sigma while the substrates were from Bachem.

Each assay included a 2 hr enzyme-inhibitor pre-incubation at RTfollowed by addition of substrate and hydrolysis to ˜30% conversion asmeasured on a Spectramax Pro microplate reader. Compound concentrationsvaried from 100 to 0.4 μM depending on their potency.

The final conditions for each assay were as follows:

50 mM Tris(hydroxymethyl)aminomethane hydrochloride (Tris-HCl) pH8, 0.5M

Sodium Sulfate (Na₂SO₄), 50 mM NaCl, 0.1 mM EDTA, 3% DMSO, 0.01%Tween-20 with:

133 μM succ-AAA-pNA and 20 nM HNE or 8 nM PPE; 133 μM succ-AAV-pNA and15 nM HLE; 100 μM succ-AAPF-pNA and 250 pM Chymotrypsin.

100 mM NaHPO₄ (Sodium Hydrogen Phosphate) pH 6, 0.1 mM EDTA, 3% DMSO, 1mM TCEP (Tris(2-carboxyethyl)phosphine hydrochloride), 0.01% Tween-20,30 μM Z-FR-pNA and 5 nM Cathepsin B (enzyme stock activated in buffercontaining 20 mM TCEP before use).

The percentage of inhibition was calculated using the formula:[1−((UV_(inh)−UV_(blank))/(UV_(ctl)−UV_(blank)))]×100

A non-linear curve fit was applied to the inhibition-concentration data,and the 50% effective concentration (IC₅₀) was calculated by the use ofExcel Xl-fit software.

HCV Replicon Cell-Based Assay

An HCV replicon whole cell system was established as described byLohmann V, Korner F, Koch J, Herian U, Theilmann L, Bartenschlager R.,Science 285(5424):110-3 (1999). This system enabled us to evaluate theeffects of our HCV Protease compounds on HCV RNA replication. Briefly,using the HCV strain 1B sequence described in the Lohmann paper(Assession number: AJ238799), an HCV cDNA was generated encoding the 5′internal ribosome entry site (IRES), the neomycin resistance gene, theEMCV (encephalomyocarditis virus)-IRES and the HCV nonstructuralproteins, NS3-NS5B, and 3′ non-translated region (NTR). In vitrotranscripts of the cDNA were transfected into the human hepatoma cellline, Huh7. Selection for cells constitutively expressing the HCVreplicon was achieved in the presence of the selectable marker, neomycin(G418). Resulting cell lines were characterized for positive andnegative strand RNA production and protein production over time.

Huh7 cells, constitutively expressing the HCV replicon, were grown inDulbecco's Modified Eagle Media (DMEM) containing 10% Fetal calf serum(FCS) and 1 mg/ml G418 (Gibco-BRL). Cells were seeded the night before(1.5×10⁴ cells/well) in 96-well tissue-culture sterile plates. Compoundand no compound controls were prepared in DMEM containing 4% FCS, 1:100Penicillin/Streptomysin, 1:100 L-glutamine and 5% DMSO in the dilutionplate (0.5% DMSO final concentration in the assay). Compound/DMSO mixeswere added to the cells and incubated for 4 days at 37° C. After 4 days,plates were rinsed thoroughly with Phosphate-Buffered Saline (PBS) (3times 150 μl). The cells were lysed with 25 μl of a lysis assay reagentcontaining the FRET peptide (RET S1, as described for the in vitroenzyme assay). The lysis assay reagent was made from 5× cell Luciferasecell culture lysis reagent (Promega #E153A) diluted to 1× with distilledwater, NaCl added to 150 mM final, the FRET peptide diluted to 10 μMfinal from a 2 mM stock in 100% DMSO. The plate was then placed into theCytofluor 4000 instrument which had been set to 340 nm excitation/490emission, automatic mode for 21 cycles and the plate read in a kineticmode. EC₅₀ determinations were carried out as described for the IC₅₀determinations.

As a secondary assay, EC₅₀ determinations from the replicon FRET assaywere confirmed in a quantitative RNA assay. Cells were lyzed using theRneasy kit (Qiagen). Purified total RNA was normalized using RiboGreen(Jones L J, Yue S T, Cheung C Y, Singer V L, Anal. Chem., 265(2):368-74(1998)) and relative quantitation of HCV RNA expression assessed usingthe Taqman procedure (Kolykhalov A A, Mihalik K, Feinstone S M, Rice CM, Journal of Virology 74, 2046-2051 (2000)) and the PlatinumQuantitative RT-PCR Thermoscript One-Step kit (Invitrogen cat#11731-015). Briefly, RNA made to a volume of 5 μl (≦1 ng) was added toa 20 μl Ready-Mix containing the following: 1.25× Thermoscript reactionmix (containing Magnesium Sulfate and 2-deoxynucleoside 5′-triphosphates(dNTPs)), 3 mM dNTPs, 200 nM forward primer (sequence:5′-gggagagccatagtggtctgc-3′), 600 nM reverse primer(5′-cccaaatctccaggcattga-3′), 100 nM probe(5′-6-FAM-cggaattgccaggacgaccgg-BHQ-1-3)(FAM: Fluorescein-aminohexylamidite; BHQ: Black Hole Quencher), 1 μM Rox reference dye (Invitrogencat #12223-012) and Thermoscript Plus Platinum Taq polymerase mixture.All primers were designed with ABI Prism 7700 software and obtained fromBiosearch Technologies, Novato, Calif. Samples containing knownconcentrations of HCV RNA transcript were run as standards. Using thefollowing cycling protocol (50° C., 30 min; 95° C., 5 min; 40 cycles of95° C., 15 sec, 60° C., 1 min), HCV RNA expression was quantitated asdescribed in the Perkin Elmer manual using the ABI Prism 7700 SequenceDetector.

Biological Examples

Representative compounds of the invention were assessed in the HCVreplicon cell assay and/or in several of the outlined specificityassays. For example, Compound 34 was found to have an IC₅₀ of 23nanomolar (nM) against the NS3/4A BMS strain in the enzyme assay.Similar potency values were obtained with the published H77C (IC₅₀ of 3nM) and J4L6S (IC₅₀ of 2.9 nM) strains. The EC₅₀ value in the repliconassay was 166 nM.

In the specificity assays, the same compound was found to have thefollowing activity: HLE>100 μM; PPE>200 μM; Chymotrypsin>200 μM;Cathepsin B>200 μM. These results indicate this family of compounds arehighly specific for the NS3 protease and many of these members inhibitHCV replicon replication.

The compounds of the current invention were tested and found to haveactivities in the ranges as follow:

IC50 Activity Ranges (NS3/4A BMS Strain): A is 10-100 micromolar (μM); Bis 1-10 μM; C is 0.1-1 μM; D is <0.1 μM

EC50 Activity Range (for compounds tested): A is 10-100 μM; B is 1-10μM; C is 0.1-1 μM; D is <0.1 μM
